Over carbonation?

[tangerang]

Hello everyone, I have been brewing about 3 years mostly all grain. I have been kegging for about a year and i have not been able to get away from excessive amounts of foam. I thought it was over carbing at the beginning, but I've tried multiple ways and can't figure it out. I don't set the psi high and shake, I follow the suggestion beer smith gives me for carbonation psi. I wait a few weeks and let some of the head pressure out before i pour the first glass. It pours about 2 oz of beer, then foam to the top of the glass. I have tried letting almost all head pressure out to see if it will pour more liquid, and still foam. I have a mini fridge with a single perlick tap. My hosing is 3/16 and about 6 feet long. If anyone has a suggestion that would be appreciated.

Cheers,

Why are you letting the pressure out? 6' of line may be a little short. You may want to increase it to a 10' line.

Is it a tower? Is the line cold? Does the line get reduced anywhere like 1/4 to 3/16 or whatever from say the shank and the barb?

I run 1/4" ID through my vent-matic faucets and 10' of line that's cold. I don't have any issues what-so-ever.

Beersmith makes the same mistake as virtually every other supposed "line length calculator" - and if the OP uses it he'll think his lines are perfect.

Otoh, if you want to use a calculator that Actually Gets It, use this one...

Cheers!

I set my PSI to BeerSmith Calculations, balanced my lines using the formula.

PSI - 1 - (.5 for every 1 foot elevation) / (3 PSI for 3/16) = hose length
22 - 1 - (.75) / 3
or
22 - 1.75 / 3
or
20.25 / 3 = 6.75'

I still had foam issues until I started using an ice cold glass and tapped the beer into the glass at an angle. Now I get a nice pour at 3.6 vol for my Weisse Bier. I think a warm glass causes foam also.

My final hurdle is that I still get foam at first because my tower lines are not as cold. I plan to push air from my kegerator into the insulated tower lines using a computer fan. That should chill the beer in the tower lines at the very top.

Thanks for the info. Hopefully i won't have to wait for my homebrew to settle after pouring any longer.
